How Do They Know It Is a Parallelogram? Analysing Geometric Discourse at Van Hiele Level 3 [PDF]
Research in Mathematics Education, 2014 In this article, we introduce Sfard\u27s discursive framework and use it to investigate prospective teachers\u27 geometric discourse in the context of quadrilaterals.

Switching from ligand to receptor anti-calcitonin gene-related peptide (CGRP) antibodies or vice versa in non-responders: A controlled cohort study. [PDF]
Eur J NeurolAbstract Background and purpose Limited options exist for migraine prevention after stopping anti‐calcitonin gene‐related peptide monoclonal antibodies. A systematic review examining the benefits of switching between different classes (ligand vs. receptor monoclonal antibody) is essential, alongside well‐designed real‐world studies.

Learning a new geometric concept: The role of working memory and of domain-specific abilities. [PDF]
Br J Educ Psychol, 2021 It has been suggested that not only domain‐specific factors but also working memory (WM) may play a crucial role in mathematical learning included Geometry, but the issue has not been deeply explored. In the present study, we examined the role of domain‐specific factors and of verbal versus visuospatial WM on geometric learning of a new geometrical ...

Functionally annotated electrophysiological neuromarkers of healthy ageing and memory function. [PDF]
Hum Brain MappWe analysed a large open resting‐state EEG dataset and found that dynamic rather than static neuromarkers better capture cognitive ageing. We clarified that individualised alpha power reflects memory performance rather than ageing. Finally, we used functionally annotated source reconstruction to reveal domain‐specific electrophysiological mechanisms ...

Re‐evaluation of erythritol (E 968) as a food additive
EFSA Journal, Volume 21, Issue 12, December 2023., 2023 Abstract This opinion addresses the re‐evaluation of erythritol (E 968) as food additive and an application for its exemption from the laxative warning label requirement as established under Regulation (EU) No 1169/2011. Erythritol is a polyol obtained by fermentation with Moniliella pollinis BC or Moniliella megachiliensis KW3‐6, followed by ...

An instrument for measuring performance in geometry based on the van Hiele model [PDF]
Educational Research and Reviews, 2016 [EN] In this paper we present the process of constructing a test for assessing student performance in geometry corresponding to the first year of Secondary Education. The main goal was to detect student errors in the understanding of geometry in order to develop a proposal according to the Van Hiele teaching model, explained in this paper. Our research

Simplest Shapes First! But Let's Use Cognitive Science to Reconceive and Specify What “Simple” Means
Mind, Brain, and Education, Volume 17, Issue 1, Page 5-19, February 2023., 2023 Abstract Children's informal and formal learning experiences with geometric shapes currently result in misconceptions that persist into adulthood. Here, we combine research from mathematics education as well as cognitive science pertaining to concepts, categories, and learning strategies to propose a more optimal progression that is better specified ...

Stimulating Understanding of Properties of Quadrilaterals Using Van Hiele’s Model: A Lesson Study
Journal of Mathematics and Statistics Studies, 2021 This paper explores Van Hiele’s Model's use in planning the tasks to identify the properties of quadrilaterals. Lesson study, a professional development program that enables teachers to collaborate to improve teaching and learning quality, was utilized to get necessary data needed for the study. The authors aimed to see to what extent Van Hiele’s Model
